COiRD KNOTTER FOR GRAIN-BINDERS.

SPECIFICATION forming part of Letters Patent No. 255,741, dated March28, 1882.

' Application filed October 5,1880. (No model.)

To all whom it may concern:

Be it known that we, WILLIAM N. WHITE- LEY, WILLIAM BAYLEY, andAsAHIIRI), all of Springfield, in Clarke county, Ohio, have invented newand useful Improvements in Gord-Knotters for Grain-Binders; and we dohereby declare that the following is a full and complete description ofthe same.

Our invention relatesto that class of knotting devices wherein there isa stationary cylinder with, an interior groove in a plane perpcndicularto the cylinder-axis, its ends approaching, but not meeting, andterminating in grooves parallel to the axis, and extending a shortdistance in opposite directions, within said stationary cylinder arotating tubular cylinder, which carries the griper-hook, and withinsaid rotating cylinder a rotating and reciprocating cylinder, which isprovided at or near its end-with a neck, around which the cord is to bewound,and a reciprocating looping-hook to seize and hold the loop of thecord, and a stud which projects from said inner cylinder through agroovein the middle cylinder 2 5 into the groove in said stationarycylinder, whereby when said middle cylinder is rotated the innercylinder is reciprocated and rotated. The apparatus constructed andoperating as above was notinvented by us, but ourinvention o relates toit; and it consists, first,in aknotter case or cylinder cast with aninterior groove to give direction to the knotting devices, and anothercase for the outside griper and cutter cast together in one piece, and aflange per- 3 5 pendicular to the axis of said cylinder, whereby saidcase may be attached to the supporting-frame; second, in the innercylinder and a thimble having their adjacent ends turned down smaller toaccommodate the retracting- 0 spring, and a central looping-hook jointedto said thimble, as more particularly specified in claim 2.

That others may fully understand our invention, we will moreparticularly describe it, 5 having reference to the accompanying drawings, wherein-- I Figure 1 is a perspective of the knotter and case inposition. Fig. 2 shows apla-n and elevation of the knotter-case. Fig. 3is a longitudinal section on line a" m. Fig. 3 is a vertical section onthe line y y, Fig. 2. Fig. 4 is a transverse sectiouon line g y. Fig. 5is a front elevation of knotter and casein position. Fig.

6 is a longitudinal part-section of the knotter. Fig. 7 is an elevationof the same. Fig.8 is a 5 section of the inner cylinder carrying thelooping-hook. Fig. 9 is an elevation of the same.

A is apart of the stationary frame of the machine, which bridges overthe receptacle and sustains the knotter-case.

B is the knottcr-case or stationary cylinder.

It is constructed in one piece of cast metal, and has the flange bprojecting in a plane per. pendicular to the axis. The cylinder is casthollow by aid of a core, and is provided inte- 6 riorl y with a groove,a, which passes nearly around the said interior of the cylinder in aplane perpendicular to the axis. The extremities of said groove turn inopposite directions and at right angles to the former course, and at oneend it cuts through the wall intervening between the groove and theexterior end of the cylinder B, as at a, for the purpose of admittingthe stud g, whereby the movements of the knotter are controlled, and atthe other end it runs a short distance in a direction parallel with theaxis of the cylinder, as shown in Fig.3. The same casting may, andpreferably does, include also the hollow cylindrical shell O,withinwhich the griper and cutter are placed. These two shells or cases, beingmade in the same casting and bored parallel with each other, must alwaysremain in proper relative positions. The front and back faces of theflange b are finished on a machine, so that they are parallel to eachother and perpendicular to the axis of the knotter-case. Saidknottercase B is then ready to be bolted fast to its seat on the bridgeA, and is certain to be in an accurate position and to remain so. 0

The case B forms the stationary cylinder above mentioned, and therotating cylinder D is fitted to its interior surface, and its extent ofprotrusion is determined by a lateral flange,

d, which rests against the face of the case B. 5 The cylinder D, at thatpart which may be called the inner end, because it is first to enter thecase B, and protrudes through the same, is made smaller in diameter thansaid case, so that it may be inserted or removed easily as a completestructure. The cylinder D is hollow, and has a uniform interiordiameter. Just behind the flange d it is cut transversely by a slot, 2',and at one end said slot is prolonged, with an upward direction at anangle of about forty-five degrees, nearly to the flange d, as shown inFig. 7. About midway between the extremities of said slot and on theexterior surface of the cylinder there is a longitudinal groove, 6, toreceive the griper E, by which the ends of the band are held while theband is being passed around the knotter.

Within the cylinder D there is the inner cylinder, F, which has at itsouter end a neck, g, with the lip h at its outer end. The revolution ofthe cylinder D causes the cord to be wound around this neck in theprocess of tying the knot.

A stud or pin, G, is attached to the inner cylinder, F, and projectsthrough the slot t'in cylinder D and into the groove a in case B. Thisarrangement effects the following results: During that part of therevolution of the cylinder D wherein the stud G is free to move in thegroove a the cylinder F will revolve with lines, Fig. 8, and the slotfor looper H is cut in said pin, so that said looper passes through thesame. The cylinder F is slotted longitudinally to receive the shank ofthe looper-hook H, which is jointed at its lower end to the thin:- bleK, and is retracted by the spring J, the ends of which are confinedbetween said thimble and the end of the cylinder F. The lower end of thecylinder F is bored out and the upper end of the piston K is fittedthereinto, so that one slides within the other, while a certain degreeof flexibility is permitted at the joint between H and K at m.

Having described our invention, what we claim as new is I 1. Aknotter-case or outer cylinder, B, with a flange, b, and an interiorgroove, a, as described, and a cylindrical shell, 0, for theoutsidefgriper and cutterfboth cast in a single piece, as described.

2. The combination of the cylinder F with athimble jointed to thelooping-hook and sliding therewith in the cylinder, the thimble providedat the end with a shoulder, and a part of the cylinder made smaller, soas to act with the shoulder on' the thinnble to guide and hold a spring.

3. A cylinder, D, combined with an inclosing stationary knotter-case,cast in one piece, and-having the groove to and a laterally-projectingflange, b, whereby said knotter may be bolted direct] y to the verticalside of the bridgeframe, substantially as set forth.
